Things you should make out of leather: Briefcases. Golf bags. Wallets. Bondage gear. Bicycle seats. Shoes. Club chairs.

Things you should not make out of leather: Jogging pants.

We admit the senseless lack of utility is high here. A pair of leather jogging pants is essentially a sign to the world that says, "No, I have absolutely no intention of jogging today, or ever."

But when we try to picture JFK wearing these things, we can't do it. Paul Newman? Nick Nolte? Steve McQueen? Johnny Depp? Nope, nope, nope, nope — not even Johnny Depp. Jennifer Lopez' fourth husband, a 24-year-old back-up record producer named Ziqué? Yes! Now we are pretty sure such a creature does not actually exist. But his pants do, and these are them.

We have been watching this Jil Sander collar for what feels like years now, wondering who might pay $1480, then $589, and now $147.25 for this item. On the one hand, we were conceptually intrigued by Sander's merchandising innovation — she was trying to appify or unbundle something that had traditionally been considered a part of a shirt or jacket rather than a standalone accessory. On the other hand, there was the item itself, which always made us think, "Damn. Somewhere, there's a really toolbaggy, circumcised leather jacket walking around." Now, months later, the snipped foreskin, er, collar, can be had for a 90% discount. And yet sizes S, M, and L are still available. Verdict: Unsafe at any price!
